Title: Ion-wind air cleaner
Inventor: TOMITA MAKOTO
IPC: B01J35/04
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent an ozone smell and to suppress running cost without decreasing wind velocity. SOLUTION: In an ion-wind air purifier wherein an ionizing electrode 1 inducing an ion wind and an opposed electrode 2 are provided in an air passage connecting a suction port and an exhaust port and suspended dust in air is sucked to a dust collection means by the ion wind, an ozone decomposition catalyst 5 having a honeycomb structure is provided on the side of exhaust port.

Abstract: PROBLEM TO BE SOLVED: To unequivocally decrypt plaintext from ciphertext, to make the ciphertext strong to a selected cipher attack and to make the ciphertext usable for digital signature by selecting the output of a second selector or third multiplier by the output of a comparator and outputting the same as the ciphertext. SOLUTION: The multiplier 131 calculates the remainder 2y mod N when the output y of a square circuit 120 subjected to division of twice y by N. The selector 132 produces the output of the multiplier 131 in the case of a Jacobi symbol (M|N)=-1 and outputs y in other cases. The comparator 142 compares the magnitude of the output (N-1)/2 of a shifter 141 and the output z of the selector 132. The multiplier 143 calculates the remainder -z mod N when -1 times the output z of the selector 132 is divided by N. The selector 144 selects and output the output -z mod N of the multiplier 143 when the output of the comparator 142 indicates z>(N-1)/2. The selector selects the output z of the selector 132 in other cases and outputs the same as the ciphertext C from an output terminal 153.
